HENGE 8A UBEC

When using a lithium battery pack of more than 3S, a switch-mode BEC offers much higher efficiency and generates less heat compared to a traditional linear BEC.

For example, consider a 4S lithium battery pack with a typical voltage of 14.8V. To output 5V/1A, the current flowing into the linear BEC is at least 1A. The power consumed by the BEC is 14.8V * 1A = 14.8W, but the useful output power is only 5V * 1A = 5W. Therefore, the efficiency of the linear mode BEC is just 5W / 14.8W = 33.8%. The redundant power, 14.8W – 5W = 9.8W, is dissipated as heat, causing the BEC to become very hot and potentially enter a protection state, rendering it unable to function.

In contrast, a switch-mode BEC can handle higher input voltages with much greater efficiency, reducing heat generation and maintaining reliable operation.
